Practical screening tools for sarcopenia in patients with systemic sclerosis.

ABSTRACT:

Introduction

In view of the method of diagnosing sarcopenia being complex and considered to be difficult to introduce into routine practice, the European Working Group on Sarcopenia in Older People (EWGSOP) recommends the use of the SARC-F questionnaire as a way to introduce assessment and treatment of sarcopenia into clinical practice. Only recently, some studies have turned their attention to the presence of sarcopenia in systemic sclerosis (SSc).There is no data about performance of SARC-F and other screening tests for sarcopenia in this population.

Objective

To compare the accuracy of SARC-F, SARC-CalF, SARC-F+EBM, and Ishii test as screening tools for sarcopenia in patients with SSc.

Methods

Cross-sectional study of 94 patients with SSc assessed by clinical and physical evaluation. Sarcopenia was defined according to the revised 2019 EWGSOP diagnostic criteria (EWGSOP2) with assessments of dual-energy X-ray absorptiometry, handgrip strength, and short physical performance battery (SPPB). As case finding tools, SARC-F, SARC-CalF, SARC-F+EBM and Ishii test were applied, including data on calf circumference, body mass index, limitations in strength, walking ability, rising from a chair, stair climbing, and self reported number of falls in the last year. The screening tests were evaluated through receiver operating characteristic (ROC) curves. Standard measures of diagnostic accuracy were computed using the EWGSOP2 criteria as the gold standard for diagnosis of sarcopenia.

Results

Sarcopenia was identified in 15 (15.9%) patients with SSc by the EWGSOP2 criteria. Area under the ROC curve of SARC-F screening for sarcopenia was 0.588 (95% confidence interval (CI) 0.420-0.756, p = 0.283). The results of sensitivity, specificity, positive likelihood ratio (+LR), negative likelihood ratio (-LR) and diagnostic Odds Ratio (DOR) with the EWGSOP2 criteria as the gold standard were 40.0% (95% CI, 19.8-64.2), 81.0% (95% CI, 71.0-88.1), 2.11 (95% CI, 0.98-4.55), 0.74 (95% CI, 0.48-1.13) and 2.84 (95% CI, 0.88-9.22), respectively. SARC-CalF and SARC-F+EBM showed better sensitivity (53.3%, 95% CI 30.1-75.2 and 60.0%, 95% CI 35.7-80.2, respectively) and specificity (84.8%, 95% CI 75.3-91.1 and 86.1%, 95% CI 76.8-92.0, respectively) compared with SARC-F. The best sensitivity was obtained with the Ishii test (86.7%, 95% CI 62.1-96.3), at the expense of a small loss of specificity (73.4%, 95% CI 62.7-81.9). Comparing the ROC curves, SARC-F performed worse than SARC-CalF, SARC-F+EBM and Ishii test as a sarcopenia screening tool in this population (AUCs 0.588 vs. 0.718, 0.832, and 0.862, respectively). Direct comparisons between tests revealed differences only between SARC-F and Ishii test for sensitivity (p = 0.013) and AUC (p = 0.031).

Conclusion

SARC-CalF, SARC-F+EBM, and Ishii test performed better than SARC-F alone as screening tools for sarcopenia in patients with SSc. Considering diagnostic accuracy and feasibility aspects, SARC-F+EBM seems to be the most suitable screening tool to be adopted in routine care of patients with SSc.

Project description:ObjectivesEarly identification of sarcopenia in patients with chronic liver disease is crucial for patient management and prevention of severe complications. We aimed to assess the effectiveness of Ishii score, Strength, Assistance with Walking, Rise from a Chair, Climb Stairs and Falls (SARC-F), SARC-F and Calf Circumference (SARC-CalF), and Mini Sarcopenia Risk Assessment-7 (MSRA-7) to screen sarcopenia in patients with chronic liver disease.MethodsThis prospective study included patients with chronic liver disease in the infectious department of a tertiary hospital in Sichuan, China. Ishii score, SARC-F, SARC-CalF, and MSRA-7 were used to screen for sarcopenia risk. Sarcopenia was diagnosed according to the Asian Myometriosis Working Group (AWGS) 2019, which was used as the gold standard to compare the performance of the four screening tools. We completed clinical registration on the Chinese Clinical Trial Registration website (ChiCTR2100043910).ResultsA total of 366 patients with chronic liver disease (22.4% women, mean age 48.96 ± 11.88 years) were evaluated. Based on the AWGS 2019 standard, the prevalence of sarcopenia in patients with chronic liver disease was 17.5%. Among all participants, receiver operating characteristic (ROC) produced an area under the curve (AUC) of 0.82 for Ishii score (sensitivity 85.94%, specificity 78.15%), 0.53 for SARC-F (sensitivity 6.25%, specificity 99.34%), 0.64 for SARC-CalF (sensitivity 45.31%, specificity 83.11%), and 0.55 for MSRA-7 (sensitivity 87.50%, specificity 22.85%). Based on AUC, decision curve analysis, and calibration curves, we concluded that Ishii score was the most accurate screening tool and was superior to the other tools.ConclusionsIshii score is more suitable for screening sarcopenia in patients with chronic liver disease than the SARC-F, SARC-CalF, and MSRA-7, based on the AWGS 2019 criteria. Nursing professionals can use Ishii score as a clinical tool to screen for sarcopenia in patients with chronic liver disease, providing an indication cue for the final diagnosis of sarcopenia, improving diagnostic efficiency, and enabling early identification and prevention of complications resulting from sarcopenia.

Project description:BackgroundSarcopenia is defined as decreased skeletal muscle mass and muscle functions (strength and physical performance). Muscle mass is measured by specific methods, such as bioelectrical impedance analysis and dual-energy X-ray absorptiometry. However, the devices used for these methods are costly and are usually not portable. A simple tool to screen for sarcopenia without measuring muscle mass might be practical, especially in developing countries. The aim of this study was to design a simple screening tool and to validate its performance in screening for sarcopenia in older adult cancer patients scheduled for elective surgery.MethodsCancer surgical patients aged >60 years were enrolled. Their nutritional statuses were evaluated using the Mini Nutrition Assessment-Short Form. Sarcopenia was assessed using Asian Working Group for Sarcopenia (AWGS) criteria. Appendicular skeletal muscle mass was measured by bioelectrical impedance analysis. Four screening formulas with differing combinations of factors (muscle strength, physical performance, and nutritional status) were assessed. The validities of the formulas, compared with the AWGS definition, are presented as sensitivity, specificity, accuracy, and area under a receiver operating characteristic curve.ResultsOf 251 enrolled surgical patients, 84 (34%) were diagnosed with sarcopenia. Malnutrition (odds ratio [OR]: 2.89, 95% CI: 1.40-5.93); underweight status (OR: 2.80, 95% CI: 1.06-7.43); and age increments of 5 years (OR: 1.78, 95% CI: 1.41-2.24) were independent predictors of preoperative sarcopenia. The combination of low muscle strength and/or abnormal physical performance, plus malnutrition/risk of malnutrition had the highest sensitivity, specificity, and accuracy (81.0%, 78.4%, and 79.3%, respectively). This screening formula estimated the probability of sarcopenia with a positive predictive value of 65.4% and a negative predictive value of 89.1%.ConclusionSarcopenia screening can be performed using a simple tool. The combination of low muscle strength and/or abnormal physical performance, plus malnutrition/risk of malnutrition, has the highest screening performance.

Project description:BackgroundPulmonary arterial hypertension is a life-limiting complication in patients with systemic sclerosis. Current recommendations suggest a minimum screening of an annual transthoracic echocardiogram and pulmonary function test. We hypothesize that modifiable provider-level hurdles contribute to inadequate screening and can be alleviated.Methods and resultsWe performed a longitudinal study over 23 months of all systemic sclerosis patients seen in pulmonary and/or rheumatology clinics. Pulmonary arterial hypertension screening was measured monthly as percentage of patients with up-to-date transthoracic echocardiogram and pulmonary function test out of the total systemic sclerosis patients with an outpatient encounter that month. Tests were considered "up-to-date" if they were performed 12 months prior or within the next 6 months post-encounter. Baseline adherence to PAH screening was assessed using a 9-month preproject period. Physicians in rheumatology and pulmonary clinics were surveyed for knowledge and perceived as barriers to screening. Interventions focused on provider-level hurdles to improve the screening rate to >90%. Adherence to systemic sclerosis-associated pulmonary arterial hypertension was compared between baseline and post-intervention phases as a continuous variable using nonparametric Mann-Whitney-Wilcoxon test and as categorical variable using chi-square test for overall adherence rate. A total of 18 providers were surveyed, of which 67% knew minimal screening recommendations and 44% identified "difficulty ordering tests" as a barrier. Our interventions were as follows: (1) didactic education and literature dissemination and (2) best practice alert in the electronic medical record to facilitate just-in-time ordering of screening. Adherence was measured for 23 months, comprising 166 systemic sclerosis patients. Monthly adherence to pulmonary arterial hypertension screening increased by 10.4% (69.2%-79.6%, p = 0.01 with chi-square and p = 0.09 with Mann-Whitney-Wilcoxon test), with an increase in transthoracic echocardiogram by 7.5% and pulmonary function test by 4.9%.ConclusionProvider-level hurdles contribute to sub-optimal systemic sclerosis-associated pulmonary arterial hypertension screening. Lack of knowledge and difficulty in ordering tests were major barriers. Structured education and decision-support aids improve screening. These interventions, however, were insufficient to improve screening to a goal target of >90%.
